The so-called Coronation Cup of Frederik III. The cup was made by H.C. Brechtel in The Hague, 1653. It is possible that it was to have been used, in a planned but never realised, swearing of allegience to Frederik III in Hamburg, 1654.
Originally the city of Hamburg was to submit to danish rule, at first through a mere symbolic monetary tribute, but this was later altered into a ceremony celebratig the danish king as their liege – which was even more insulting. Ultimately this ceremony was never carried out, and the city remained independent. The reason why the danish king could claim supremacy over Hamburg was the ownership of the bordering duchy of Stormarn. The cup has been decorated with various insults and symbolic provocations, such as the danish lion who has in its mouth the swan representing Hamburg.
